Effectiveness of extracorporeal shock wave therapy in chronic plantar fasciitis: a meta-analysis.

Abstract

The objective of this study was to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) in treating chronic plantar fasciitis. An online database search was conducted for studies using ESWT in managing chronic plantar fasciitis. Eleven high-quality randomized controlled trials were included in the meta-analysis and showed that ESWT was more effective in reducing morning pain (weighted mean difference, -0.77 [95% confidence interval {CI}, -1.30 to -0.25]; odds ratio, 0.65 [95% CI, 0.42-1.00]). Moderate-intensity ESWT was more effective in decreasing overall and activity pain (weighted mean difference, -6.6 [95% CI, -6.74 to -6.46], and weighted mean difference, 0.47 (95% CI, 0.30-0.74). Both moderate- and high-intensity ESWT were more effective in improving functional outcome, with odds ratios of 0.51 (95% CI, 0.30-0.84) and 0.47 (95% CI, 0.29-0.75). The adverse effects that were seen more in ESWT were pain on the calcaneal area and calcaneal erythema. This study concludes that moderate- and high-intensity ESWT were effective in the treatment of chronic plantar fasciitis.
